I have been very impressed with the battery life I've been getting on my Nexus. the talk time has been much higher than any phone I've owned. Here are a few screenshots of my battery life. These two days are pretty much my normal day (lol yeah I talk a lot on the phone).
The first post will be the day that about 50% of the time I was on wifi.
The 2nd post will be screenshots from a day of being connected to hsdpa for the entire day (no wifi at all).
My setup: I use push email, facebook sync, auto brightness, gps on, bluetooth on.
Also, when the phone first came I charged it completely then ran the battery down until the phone shut off. I then charged it completely without removing it from the charger.
Below is the day where I was connected to wifi about half the time:
These screenshots show the next day where I used no wifi at all and was connected to hsdpa the entire time.
I have had mine for 2 days, and I have to say it seems to have pretty good life as well, compared to my Atrix and Note. After reading about all the gripes here,
I was expecting the worst. This battery will more than get me through everything I need to do with it in my day, but I suppose it all depends on what you do with the phone.

Coming from a G2x with a terrible 10 hour battery life, anything I get out of this is freaking fantastic compared to it! I Just wish the devs start getting out some UVed kernels so I can make it longer through the day! I consider myself a heavy user/texter (girlfriend ) and so I'd like to get through the whole day (~18 hours) without a charge I must say, I got to 16 hours yesterday and I was really pleased with that, never had a stock rom last so long without any tweeks!
this is my battery life after first day ....
Not to shabby haha

mysterioustko: I think you're usage is a bit different to the average user. With all that talk time you're using the screen a lot less. It seems the screen sucks a lot of power, and if you're not using it often a full charge lasts 4 to 6 hours longer.

I typically average between 1-2 hours of screen time on an average day. But I talk A LOT each day lol. I'm impressed with the talk time because I've yet to see a phone besides this one that can go 6 hours of talk time in the real world when connected to hsdpa. Also, if you think about it, 1.5 hours of screen time is decent use. It's not a massive amount of use, but it's definitely not like it's getting no use. All in all I have been pleased with the battery life.
I don't know about you guys but im very disappointed in the battery life. With wifi turned on the entire day and no calls, just browsing and chatting on google talk, i got 3 hours 54 mins of screen on time before the phone reached 12% battery. I think thstss pretty horrendous. I was hoping for 7 hours or something of on screen time. My galaxy tab 10.1 has spoiled me i guess. Illl live with it because theres no other android phone im aware of that will give me more, but im kinda bummed about it.
My iPhone 4 has insane battery life... I cant imagine having less. Hopefully they sell larger batteries + backplates for the Galaxy Nexus?

Same here tbh. And the really frustrating part is, I only have 2G where I live so I was hoping to see really great battery life. Hasn't been the case so far though.
However having said that, just last night I flashed XXIK6 and while it's still very early to say for sure, it "appears" that battery life has significantly improved for me. Currently sitting on 91% after 3.5 hours with very, very light usage, IE: 15-20 mins screen on, 15 min phone calls, etc. Nothing to write home about sure, but way way better than before. It would normally be around 80% by now.
It's really sad when the very first thing you do after unlocking your phone is to go into setting to check your battery. Wish I could stop obsessing and enjoy this marvelous device without having to worry about it.
What did you guys do after getting the phone.
Did you charge it all the way to full before use, use and charge at the same time, or let it discharge all the way and then charge it to full?
Thanks.
I would have to say that the GN has the best battery life of any of my previous android phones. (G1, N1, Sensation) These things are very subjective though.

Yeah, and I don't want to lose the thinness of this gorgeous phone with an extended battery, but 4 hours of screen on time? Anyways, can you let us know how that radio works out, I'm not expecting much, but still curious. If it is noticeably better, I will try to unlock+root this phone. I'm just a little scared to brick this 700$ device.
I'm just waiting for mod of web browser that will invert colours. Black backgrounds and white text ...that would extend battery life significantly. I swapped colours on xda app and pulse reader only browser left ha ha

Yup, it's under accessibility in browser settings. Great if you read mainly text-only sites since it inverts image colours as well
2-3% per hour idle
I did a benchmark this afternoon for about 8 hours.
ITL41F rom, rooted + dcm kernel, otherwise stock. bluetooth, HSDPA, 1 gmail sync, and a few background sync that is very light.
idle the phone in home for 8 hours. the battery drops about 2-2.5% per hour consistently.
how long does it last with 'constant use' though?... from fully charged, to then having the screen on the whole time & doing web browsing, video watching, downloading, etc... (with data on, not wifi)

I'm sure we all know that the battery life on the G Nexus is pretty awful, so let's all go star and comment on the issue so we can get Google's attention!

Just scroll all the way down to the bottom and star the issue or leave a comment too.
Done and done... I hope this comes before I need to return the VZ GNex
Hmm, compared to my EVO 4G, I barely had to do anything to this to get the battery life to be very good (estimate 100 -> 0 = 15hours). Maybe I use the screen less than you guys though.
At home, no LTE connection. 5.5 Hours.
On GSM.. battery life is stellar.. keep in mind, like the person who posted above me that if you are in a low signal area your battery will be destroyed searching for signal..
Yeah I don't have LTE where I am either, but I have it forced to CDMA only. Android OS is my battery killer. I usually get around 6 hours before having to plug it up.
I really think that if enough people starred the issue then it will get someones attention! (Crosses fingers)
Please star, but don't comment. There is enough useless comments there already, and everyone gets notified on new comments.

you probably have a rogue app killing your battery. if I let my nexus sit idle with LTE on I get close to 2 and a half days
Hi,
This high Android OS Keep awake time is not specifically about battery life issue.
We are discussing the fact that, because of this, the phone is constantly waking up (wake up state).
And that's should not happen while the device is turned off, for example.
Yes, of course, this will relate to battery life at the end. But, that's not the point of the discussion / bug as everybody has different preference of battery life. One can say 12 hours is enough, while others may say 24 hours is not enough, according their usage pattern.

i aint charged in 3 days so im all good
This is nothing new. Android is a batt hog, plain and simple. You think google doesnt know this already. Its an "acceptable" item. Where they know about it & it's not the best, but thats what they get if they want a phone thats constantly using the network, has a large HD screen and is so damn good to look at you wont want to put it down.
Quit itchin and get on with it....
I have the extended battery from Verizon so keeping that in mind, my phone lasted 14 hours with 10% remaining with normal use. I stopped testing since I had to go to sleep
By the way I have Beweather and Facebook updating every hour and Pulse updating every 6 hours. I also have endgadget, Cnet, Google currents, Flickr and 500px updating.
So far battery life is a bit lower than I would like but not to a horrible state. definitely going to need the extended battery though. playing around today to see how fast I can kill it.
can't get photo to upload now though for some reason but got 2 hours 10 minutes with 12% remaining. would kinda like to see that as a stat added to phone reviews, minimum battery life. Max is fine but I'd rather know how long it will last with power using.

I'd say battery life was less than great on 4.0.1 but 4.0.2&.0.3 its pretty damn good now my idle usage is next to nothing. 2 days ago i had 47 minutes talk time, 1h38m screen on and about 13-15 hours of idle and still had almost 40% left at midnight.

I think you don't understand.
This is not about battery life, but the high Android OS Keep awake time. Which means your phone was awake when it's turned off.
Obviously, this doesn't happen on my HTC Desire, nor Nexus S with Gingerbread.

I can't speak for battery life on the LTE Nex as i have the HSPA+ version...I've found that the battery life is quite excellent after a few charge cycles...Have gotten 21hrs on a single charge with normal usage...if i'm watchin vids or playin games then im putting my phone on the charger cuz the screen really does eat up battery alot.
My two Brothers just picked up the unlocked GSM Nexus off the Play/Market store last week. One has it running on pre-paid T-Mobile, the other on Straight Talk ATT, and their battery life is ****ing unbelievably better than what three of us get on the Verizon Nexus, and we are not using 4G/LTE at all.
Both my Brothers use their phone at work, no Wifi just the 3G signal, and they both text me this week telling me battery life %. Right now after 4+ hours unplugged they both around 85%-90%, not using it except sending several texts and reading websites. And after a work day unplugged for like 10 hours they both have like 70%-75% left.
Now myself, my Wife and buddy have the Verizon Nexus, my Wife barely uses her phone at all, and at lunch time will be at like 70% battery left, and after getting home still unplugged for 10+ hours she's at like 45%. Where my Brothers with same use would be at 70%.
My buddy has the same as my Wife's usage, no WiFi wither, not using phone much and his phone is at like 40% after 12 hours or so. Both of them have 4G/LTE off and GPS off, and no sync on.
I use my phone a lot for work sales calls, and I am in the red by like 4:00pm, I get maybe 7 - 9 hours of use on a busy workday.
My Brother on the GSM T-Mobile, said after 23 hours his phone was at 45% battery life, and that was him using it quite a bit, dozens and dozens of texts, lots of websurfing, tons of e-mails. Our Verizon Nexus would never get that kind of battery life.
It is known. What really matters though is screen on time.

I agree screen time is crucial. But my Wife uses her Verizon Nexus very little at work and by time she comes home is at like 45% battery after about 12 hours or so. My Brother on GSM Nexus after 12 hours and using it a bit more would be at 70% battery.
That is a HUGE difference in battery life with very similar use.

do they work in the same building?
if your wife works in a place with not as good of a signal, i expect her battery to drain faster as the phone is trying to get more signal.
I installed AOKP 5 on her phone last night. Her battery seems much better. Unplugged for 7 hours at 80% battery now. That is a major upgrade. But again she barely uses her phone at all during work, pretty much just sits there. Where my Brother with same use today is at 90%.
I am running CM9, unplugged for 6 hours at 35% battery, but I use my phone a lot during work. Have 2.5 hours screen time. Tons of texts...lots emails...several phone calls....web surfing.

With GSM you can expect around 3 hours screen time and tons of standby time.
The standby time is great, but the screen time is somewhat mediocre to me.
Some days my battery just gets ate and others (like today) I'm having good battery. Usually I'm finding that apps are open in the background even after I hit back to "close" them. So if I keep up on the "Recents" menu and swipe it all away, I see an improvement.
I'm waiting for the MIUI styled "X" that closes ALL recent apps in one strike. Every little bit helps. An older version of Gummy (x.8) I had insane battery life. From 8am-3pm I would still have like 75%. I'm running LiquidSmooth right now and at 3pm I am at 60%. This was with 40 emails and 2 20min calls. No texting today
But LiquidSmooth has more options and is much faster then Gummy, so IMO the small battery difference is a good trade off. Later Gummy versions seems to consume more battery while lacking in the features.
AOKP never ran well for me in either the performance or battery department. Seemed to be laggy AND battery lousy. However I haven't played with it in a few weeks.
I too keep 4G disabled but I also have WiFi on all day (I never turn it off). I also use "Bluetooth On Call" which enables my bluetooth while on a call, so I can use a wireless headset. It automatically disables bluetooth, but I'm sure it consumes more battery then a normal call.
I only have 40minutes of screen ON time too. Mostly quick checks of emails. A few turns of WordFued and DrawSomething. I do work in a dungeon with little/no signal, which I suspect eats it up.

But it depends what you do in that screen time. If you do a lot of gaming and browsing with 3 hours it's great. If you just swipe through the home screen and send a couple text message with 6 hours of screen time, not so great.
A cool test would be to turn on airplane mode and play a movie. I'd be interested to see if it has something to do with programming vs hardware.
Then the same test with 3G.
Both really need to be setup similarly, same wallpaper, apps, etc, to really get a good measure of comparison
This isn't a news flash. Its been pretty well known.

Well, yes and no. Gaming does use more cpu and such than just flipping through your home screens so I see where your coming from and agree to an extent.. But also consider that display is almost always the biggest battery consumer in battery stats, regardless of what you are using it for.
If you switch the 4G off then it will be a different story.

If you really want to compare the battery on all those phones, at the end of the day have your wife, your buddy, your brothers, etc...send you a screen shot of their battery stats. There are so many reasons why your battery life can change, and unless you are following someone all day then you really won't know the full picture.
And yes I usually say screen on time is a better "quick" comparison of battery life. Someone who has a display timeout of 1 min compared to someone with 5 min will have significantly different battery results, even with similar usage.
LTE is a *****.

CDMA radio technology is a bit worse on battery than GSM, I'm betting that's where most of the difference comes from (LTE excluded obviously). With my screen on constantly, I've gone over 5.5 hours of screen on time before on my VZW GNex with about 50% 3G/50% WIFI usage. Again though, that was almost constant screen on from 100% to 0% battery. I've also watched the entirety of LOTR: Return of the King Extended Cut (4:20 minute run time) with my phone while also having 2 or so hours of standby on one charge, but I was in airplane mode for the majority of the movie watching. The screen is absolutely the worst battery killer by leaps and bounds and that will hold true no matter the variant.

True, it always is the biggest battery consumer as anything you do on the phone requires the screen to be on. But it also depends on what kind of users we are. If you use your phone mainly for calling and texting and emails, then 4+ hours of screen time with a total of 16 hours should be good and doable. But if you do a lot of gaming, browsing web, tasks that are heavy then 3hours+ on screen time with a total of 10-12 hours on the chart is pretty good I think.
I agree with a previous poster, screen on time is all that matters. That's why I got an ugly humpbacked Trexcell 3800 battery. Now I get 5 1/2 hours of screen on time on my Verizon GNex. Great when compared to my old time of about 2 hours.

None of us on the Verizon Nexus have 4G on. We all leave LTE off.
So why is the GSM version getting substantially better battery life ? Seems to be at least a 25% difference, if not 1/3rd better battery life on the GSM Nexus.

See my post above. CDMA radios are slightly worse on battery than GSM radios.
Like I said, I've seen 5.5 hours of screen on before once and 4+ many many times. I highly doubt the difference in battery between my VZW Nexus and a GSM Nexus under constant use from 100% charge would be more than +/-5% in either direction so the difference is somewhere in the standby times of the two devices ie. GSM vs. CDMA radio.
This is from my first full charge cycle. Completely stock. Amazing! This is 3.5 hours screen on and 2 hours voice calls. It's not letting me upload those screen shots for some reason.

Yeah mine has been pretty solid as well. Yesterday after 17hrs I was still at 35% which is better than most Android phones I've had.
I really think that galaxy nexus standby is amazing but the screen is the only thing that really drains the battery. So if you don't use it heavily, you should be fine. I use my nexus moderately and I still get through a day with about 40% left.

Pretty good... i find voice calls and cell signal to be main battery drain cause on Sprint's turtle 3G network.
With 2100mah extended battery, 15% juice left unplugged at 8:30am, replugging in at 10pm, 2.5hr screen, 1hr gps, 30min voice

Here are the results from my 2nd full charge cycle:
40+ hours off charger; 4.5 hours screen-on time. Remarkably good.
How are you getting such good battery life? i can't seem to even last a whole work day, requiring me to charge before I leave the office.
I just got my replacement, so hopefully it will be better this time around.

I use 30-40% brightness. Black wallpaper. Other than that, nothing special. I only have 1 gmail account syncing, unlike some of the people on here that have 3 or 4 email accounts syncing. I also only have like 2-3 widgets running (beautiful widgets smaller home, audiomanager pro, astrid, and maybe one or two others). And most of the screen on time is doing relatively simple tasks like web browsing, reading xda, google talk, etc. Nothing too terribly intensive like video.
Based on my experience though it seems like pretty much anybody except the heaviest of users should be able to get at least a full day's use out of it, and lighter users should easily be able to get 2.
Is yours GSM? I hear the Vzw/Sprint ones get far worse battery life.

I agree. I ended a day with ~70% battery left, and most of my usage was the screen (~30 minutes or something). I haven't had any issues with my battery dying on me yet. If I left the screen off all day, I could probably use 10-15%.

I'm guessing it isn't using LTE. If I only connect by wifi and turn off data syncing then I can get more than a day too (with moderate use).
LTE really drains the battery.

Correct it is gsm, not lte.
That's impressive! Stock rom allows you to get at least 20 hours of WiFi/3G with 3-4 hrs of screen. Auto brightness. Here in Europe we don't have LTE, so our batteries could last a little bit more.
avarage battery use is over 13 hours (cm9+franco kernel).
10 hours and 53 min it dropped to 94% worth mentioning I didn't even touch the phone, can't seem to post a screen shot of it
Right now I am at 45% and I used it quiet heavily today
I didn't charge the phone even if it sems like it

Some of the best I've seen so far from my phone (about two weeks old) is posted here. Almost 36 hours of uptime! Wifi on the whole time, had a signal for most of it too, but guarantee there were some times that I didn't (because I was trying to use the phone then). This includes time spent playing some games as well. I've fired up Osmos HD, Everlands, Swords and Soldiers, and Draw Something at some point during that charge for at least a few iterations of play on each game. Decent amount of browsing, including hits from Google Shopper for some price comparisons. I'm syncing one Google account and one Exchange account, with black wallpaper, auto brightness (not tuned) and the calendar, news and weather, settings, and prepaid usage widgets. Stock ICS and unrooted.
i have ext battery and can run (what seems like) forever
Currently running Jedi x11, and have had if for about a week now in order to test if there are infact major improvements.
I never really sat down with a timer and timed how long it took my phone to deplete, or charge, so I won't have an exact time duration for these, but I can confidently say, that since I got Jedi x11 on here, two things have started to happen.
1) Battery takes a very extended time in recharging. Both when in use, and set aside. - Previously, my battery would fully charge anywhere from 1 1/2 - 2 hours from about 15%.
2) My battery is depleting ridiculously fast. I type fairly fast, I'd say about avarage, and just for an example, I started this thread at 93%, and at this very moment, it's now at 91%... Even when not in use, the battery seems to deplete at a much faster rate. Tethering is also very draining now. - Previously, again, never timed it, but I am sure by the constant use of my phone that I've had for some time now, that this wasn't ever the case before.
This is just my observations: It would seem Jedi helps when the phone isn't in use. I'm not sure if this mentioned CPU sleeper helps with that or not, it's hard to tell as like I said, the battery goes down even when no major screen time is in use. Maybe it's something I have to turn on? Maybe not. Another, observation, when I am actively using the phone the battery will drop fast. Like, double fast.
And lastly, I observe the battery life will stay on a certain percentage longer than it does others. (Currently 89%) I took about 10 - 15 minutes writing this.
Any thoughts? Thanks for any replies I do get.

Currently running Jedi x11, and have had if for about a week now in order to test if there are infact major improvements.
I never really sat down with a timer and timed how long it took my phone to deplete, or charge, so I won't have an exact time duration for these, but I can confidently say, that since I got Jedi x11 on here, two things have started to happen.
1) Battery takes a very extended time in recharging. Both when in use, and set aside. - Previously, my battery would fully charge anywhere from 1 1/2 - 2 hours from about 15%.

I'm glad I'm not the only one with this problem on this rom. Phone takes 9 hrs to fully charge, I was starting to think I'm going crazy. My battery will charge fast if I go back to stock. But I would hate to go back because of this.

Well guys, I'm not sure what's going on, but, it should be noted. The Battery on this thing just lasted the entire evening from last night (7pm) up until now, with about the same amount of use that I did the days before when I noticed abnormal battery depletion.
Currently at 47% and I've yet to charge the phone. Of course that is with the fact that I put the phone in airplane mode while I sleep for a few hours. I watched a lot of video, listened to audio, and it's as if they thing knew I wasn't pleased with what was happening, it's now behaving like it should.
This happened a few days ago also, where the battery lasted 16 hours and was at 27%. So this leads me to think it's something that happens on and off, and I have no clue what triggers it. phone ussage rains the same. Took about 5-7 minutes writing this, and the battery marker only went from 47%, to 46%.
Credit where it's due.

a lot of factors involved when it comes to battery. based on my experience, try to see what's going on with your system using this thread. noted post 1-3. also investigate about your kernel. i am using perseus kernel and my charging time is pretty good improving than on stock :good:. also i can undervolt CPU.
where you at and which service provide you use, again, have impact on this case. i used to be with t-mo and now trying h2o (att mvno) and my battery is dropping faster when i use data. i believe since at&t coverage is suck where i am at, specially when indoors, thus phone radio has to work extra harder to get reception and shorten battery's life.

In the early days of Android CPUs were not very efficient. Undervolting helped battery life. That is no longer the case. Most good kernel devs will tell you they hate under clocking because it has a placebo effect and makes their kernel unstable.

thanks ronnie. it's good to know. wondering why some of them (well known, i believe) still offering CPU voltage adjustment (up & down) if they see it inefficient ? is it because the kernel still in beta thus come with tweak utility ?
Yeah, there is definitely something awkward going on. I took my phone out of airplane mode this morning and started viewing FB for a couple minutes; a battery that was at 98% is now somehow at 92%. It's definitely on and off. I wasn't even watching any videos or anything like that.
Would all the apps that are in ram be sucking juices this badly? I had to terminate a lot of em just a minute ago. Or, is this thing somehow giving me a false charge reading? Battery seemed to charge faster than usual last night.
I'm not even fully certain the devs read these question forums at times.
I'm runnng the international XXDMB6 based ROM on mine and currently, I'm at 76% with only an hour and 3 minutes of screentime?
I don't use Wi-Fi.
My LTE signal is rather poor.
My screen generally stays around 50% but it's on auto.
Of course I let my apps sync. But that's pretty much just gmail and facebook.
I have my weather set to sync once every hour.
I uninstalled the apps that are pretty much bloat (flipfonts, the hubs, the samsung live wallpapers, musicFX since I use DPSManager, Samsung's music app and that's all I can think of)
I'm running Perseus's kernel with about 200-350mV undervolts.
Is it truly the poor LTE signal that's taking such a toll on my battery life? I used to average 5-5.5 hours before my battery dies. Now I'm betting I'll only get around 4. When I had Verizon, the power draw from LTE was unnoticeable from 3G. Is it really that different on GSM phones?

Battery life is very noticable with lte. Reason being that volte doesnt exsist yet so two or more radios jeed to be active at the same time.
Im suprised you couldnt tell a difference on verizon, it was night and day for me.

I found Battery Drain Analyzer helpful. I kept it running for a couple of months and was able to determine which apps consume the most power (widgets, by far). But, after having spent hours trying different underclocking configurations without success, I ended up buying three extra batteries. It's really awesome to not have to worry about it. I just keep them in my pocket and swap them out as needed. It's not a very technologically advanced solution, but, it sure is effective. I use this Charger for the spares. It takes a long time to charge the batteries, but charges them fully to 100%, whereas, charging the battery in the phone doesn't seem to work as well.
